Re: [gpfsug-discuss] Upgrading kernel on RHEL

I have run into the max_sectors_kb issue and creating a file system when moving beyond 3.10.0-327 on RH 7.2 as well.  You either have to reinstall the OS or walk the kernel back to 327 via:

My 2 cents
 
And I am sure different people have different opinions.
 
New kernels might be problematic.
 
Now got my fun with RHEL 7.3 kernel and max_sectors_kb for new FS. Is something will come to the FAQ soon. It is already on draft not public.
 
I guess whatever you do .... get a TEST cluster and do it there first, that is better the best advice I could give.

All,

 

As a general rule, when updating GPFS to a newer release, would you perform a full OS update at the same time, and/or update the kernel too?

 

Just trying to gauge what other people do in this respect. Personally I’ve always upgraded everything at once – including kernel. Am I looking for trouble?

 

Cheers

Richard
